TO ALL WHOM IT MAY CONCERN:

Be it known that I, SYLVENUS WALKER, of New York, in the county of New York, and State of New York, have invented certain new and useful improvements in Pliers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe accompanying drawings, which form part of this specification, in which the marks of reference correspond in all the figures.

One important object of my invention is to so combine two or'morc implements in one, so that the implement' shall be susceptible of a greater variety of uses than they both would be separate. Another important 'object is a distribution of the metal in such a manner as' to give greater strength to those parts of the implement most liable to break, and that such changes in form shall serve a further desirable object. And another desirable object is to produce an implement combining the characteristics of ilatpliers and Vgas-burner pliers, and also further uses, without increasing thercost materially. I accomplish these and other desirable objects by constructing the jaws of dat pliers with acurve near their intersection, being made either smooth or having serrated teeth upon their inner or grasping surfaces; also, I construct this curve by bonding the metal'outwards, so as to leave greater strength in'this portion of the jaws, where the greatest amount of strain comes when in use. Furthermore, this swell or curve upon the outside of tho jaws forms a fulorum in using the `dat portion of the jaws. I further construct the flat jaws either smooth or provide them with small V-shaped grooves, extending from the curve and. terminating in a point .before reaching the outer end oi' the jaws, being parallel with the same, which serve for clasping in armmanncr round rivets, screws, or small wires, to adapt and apply them to their various uses. It is evident that the V-shapcd grooves may be constructed without regard to the curved position of the jaw.

To enable others to make and use my invention, I will proceed to describe the construction and operation of thesamo. In the drawings annexed- Figure 1 lis a perspective view of my invention, showing the gas-burner pliers and ilat pliers combined.

Figure 2 is a view showing a bolt being grasped by the V-shaped grooves in the ilat jaws.

Figure 3 is a view of the implement where the curve or fulcrum is brought into use.

In the drawings annexed AA represent the jaws of flat pliers having at their rear ends curved serrated s urfaces, B B', forming gas-burner pliers, from which extend V-shaped grooves, s s', for holding rivets, screws, bolts, or other articles, as shown in g. 2. C C' are curves formed by bending thc metal outward so as to ,form 'the opening to admit of being applied to a gas-burner for removing or applying the same; also forming the fulcrum, as shown in iig. 3. D D represent two handles to operate the implement by, which are constructed in the usual manner, except the rear ends of which are curved nearer together so as to form a better handle for the purposes shown in iig. 2. The joint is formed 4in the usual manner by one passing through an opening in the other, and a rivctthrough them both, that forms apivot. The curved serrated surfaces will also serve to hold round rods or bolts to turn off a rusty nut, or for holding fcrrules to apply them to or remove them from handles, and various other uses. The jaws thus constructed are better adapted to any of the uses for which the ordinary pliers are used. Thus I am enabled to produce a plier" having all the characteristics of both when constructed separate; and further, several decided advantages by being combined in one implement, which will render the combination as particularly adapted to the wants of every well-regulated household, and to the mechanic an indispensable article. The whole may be constructed of cast stoel, or a cheaper article may he constructed of wrought iron, or the jaws may bo faced with cast steel.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is v Pliers constructed and arranged substantially as and for the purposes herein set forth.

SYLVENUS WALKER.
